Chapter 12: Room of (Almost) Doom

Tropes That Appear In This Chapter:

Internal Reveal: It's in a conversation on the way up to Bruno's vision-cave where Hiccup tells Mirabel how he met Toothless and that he's a Viking.
Mythology Gag: When their toucan companion flies out of the room in terror, Hiccup yells "Thank you for nothing, you useless bird!"
Ship Tease: To get swing across the chasm, Hiccup and Mirabel have to hug each other closely (albeit a little awkwardly).
